WWW.SERVERCASE.COMPlease note that for the Riser card in
1U to function properly, the slot that is exactly 7.2"(B-position slot) away from the keyboard
side has to be "correct" slot type or you will have
to purchase a riser card with Ribbon cable.

1U requires Low-profile
CPU cooling fan less than 1 inch in height.

Be Careful! MB with "vertical" Aduio ports may be too tall to fit in some 1U cases but our RMC-1G-0, RMC-1GP4, RMC-1A, 1B, 1K, 1P, 1D, 1T, 1M, 1L, 1H, and 1Q have an I/O shield for such MB. Those models can take MB with vertical Audio ports, see I/O shield pictures below for reference! It's safer to use mainboard with horizontal Audio or with no Aduio on board. You may have to unsolder the vertical Audio ports on the MB if you insist on using that kind of MB in the some 1U cases.
